Abstract
For waveguides whose geometries are described as coordinate surfaces in circular polar coordinates, a finite-element method is used to derive base matrices over a triangular element in the polar geometry. These matrices are used to solve,mode problems in circular, sector, double-ridged circular, and spiral waveguides. The discussion is mainly in terms of cutoff frequency, bandwidth, and convergence.
